rootiest 2ce8bebf29 docs(functions): drop backticks from doc-headers
CONTRIBUTING states doc-headers are written as plain text -- the header
is read as-is by config-help, by funcsave, and by anyone opening the
file, and docs/codespans.py adds the site's inline code spans at render
time. 22 files had drifted from that, carrying 41 hand-written spans
that reached config-help and the man page as literal backtick
characters inside an otherwise verbatim block.

The one span whose content ended in a space is requoted rather than
dropped, so "read> " keeps reading as a prompt string.

# DESCRIPTION
# Returns the current value of a named variable in the specified scope by
# parsing set --show output. Outputs "on", "off", or "DEFAULT" (when

# in fish's internal terminology.
#
# ARGUMENTS
# varname Variable name without $ prefix
# scope "universal" or "session"
#
# EXIT STATUS
# 0 Always
#
# RETURNS
# "on", "off", or "DEFAULT", printed to stdout
#
# EXAMPLE
# set result (__config_settings_get_val __fish_config_op_aliases universal)
# # result == "on" | "off" | "DEFAULT"
